I'm guessing my card is recent (picked up from Best Buy a few days ago).

That's something I never even tried!  The noise really matches exactly when
the DMA would be used and then stops when the DMA would be cut off (only
during playback)... but the noise is very analog, not like regular clicky
or sounds that "sound" like driver problems.  It really sounds synced to one
of the hard drives in the case (probably the 10,020 RPM 9.1 GB that sits
right near the sound card).  This is something to try, and it won't even
require I shut off the machine.  :)  Which I might do anyway, 2.1.126 is 
out.
